DOM Navigation Indications

Overview

Customize your application’s performance management by capturing a wide range of browser document navigation indications. Collecting DOM navigation data allows you to:

Identify the component with the longest load time.
Measure the time required to load or unload a document.
Pinpoint slow-loading phases to identify bottlenecks.
Determine when key content becomes interactive or visible.
Trace issues such as rendering delays or excessive redirects.
Monitor loading performance across various user devices, browsers, or networks.
Support SEO optimization efforts.

Your browser document navigation indications are stored in the cx_rum.web_vitals_context field. For example, cx_rum.web_vitals_context.domComplete.
